Abstract

Abstract

In this article the behavior characteristics of selenium in the process of rhenium recovery by ion exchange and the effect of selenium on the adsorption properties of ion exchange resin were discussed. Results showed that in the adsorption process of rhenium, most of selenium, dissolving in the spraying water, was adsorbed by ion exchange resin. The saturated adsorption of rhenium was apt to achieve than selenium. In the desorption process of rhenium, most of selenium was eluted and enriched as SeO₃^2-. XRD analysis of deposit in desorption solution showed that part of SeO₃^2- was reduced to elemental selenium soon. As a result of adhering to resin by the colloidal elemental selenium, the color of resin changed to brown red and the adsorption performance of resin decreased. The elemental selenium adhering to resin could be eluted by reagent A and the adsorption performance of resin, which had been treated by reagent A, gained a certain amount of recovery.
